```

### SDK

To get the I/O APIC details, you need to use the following function in `libhyperdbg`:

```clike
BOOLEAN
hyperdbg_u_get_io_apic(IO_APIC_ENTRY_PACKETS * io_apic);
```

### Remarks

Starting from **v0.11**, this command was added to the HyperDbg debugger.

{% hint style="warning" %}
This command operates under the assumption that your computer has a **single** I/O APIC, which might not apply to multiprocessor systems, where multiple I/O APICs are common. Additionally, it assumes that the I/O APIC has not been relocated from its default address (e.g., by the BIOS or operating system) and is positioned at the standard location, **0xFEC00000**.
{% endhint %}

This command is guaranteed to keep debuggee in a halt state (in Debugger Mode); thus, nothing will change during its execution.

### Requirements

None
